Which is wrong. We're talking about natural selection of economic systems. The biggest profit (over the long term) is the measure of fitness.
Last time I checked, gold didn't reproduce.
While profits certainly contribute to the ability to reproduce, they are merely a means to an end and as such profits are a secondary but not a primary measure of success.
It's akin to measuring number of germs killed. The real desired outcome is amount of disease prevented. Sometimes killing germs leads to disease prevention, but not always. And as such, number of germs killed is not the optimal measurement of success. Disease prevention is.
With profits, they are like killing germs. Sometimes the most profitable system does not lead to the best outcome for human beings. Human outcome is the best measure, not the indirect measurement of profits.
That's not true either. An individual tragedy of the commons won't "crash" capitalism. We've already seen this.
An 'individual' tragedy? Apparently you don't know the story. Overgrazing leads to everyone's cows dying, not just the individual who added the first extra cow.
Says who?
In a capitalist economy? When, exactly?
I am referring to peasant revolts which have occurred against the aristocracy over and over in recorded history.
What do you do here, reply before you read the answer to your question? Read the post before you waste my time.
Except that this is not what happens. Research into new antibiotics continues apace.
Right. And guess who funds that research? The government! Without public funds the drug companies would be unwilling to tie up their capital in R&D that only promised long term return.
BTW, we needed new antibiotics years ago. Only now that drug resistant strains have become pandemic are we seeing any new drugs developed. The market is here now. But lots of people have died of untreatable infections in the meantime. And the few new antibiotics that are out of the gate have had major side effect risks so far.
Except that, again, this is not what happens. We do get better drugs. Not consistently, not guaranteed, but research is funny like that.
You don't know much about this field, do you? Have you ever looked into just how much public money goes into drug company R&D so the public need is met?
... Provide some sources supporting your above claims that market forces are driving ALL new drug innovation. There's a lot of money going into many new drugs that there is no current solution to and a huge market awaits: weight loss, anti-aging, Alzheimer's, cancer treatment, some vaccines...
That's why I said a mix is called for. But without public dollars, the outcome of pharmaceutical R&D would be optimum for drug companies, but not optimum for the human species.
